SPECIFICATION forming part Of Letters Patent NO. 697,786, dated April 15, 1902.

Application filed June 14, 1901. Serial No. 64,550. (No model.)

To (l/ZZ whom it may concern.-

Be it known that I, HENRY 0. BLACK, a citizenof the United States, residing at Oakland, county of Alameda, State of California, have invented certain new and useful Improvements in a Combined Bottomer and Orimper for Can-Bodies; and I do hereby declare the following to be a full, clear, and exact description of the same.

The present machine is more especially adapted for use in the manufacture of cans to be used in connection with the vacuum process of sealing fruit, vegetables, or other articles; and the object of the invention is to provide a machine whereby bottoms may be forced onto canbodies, while at the same time the open or head end of the can-body is crimped, so as to form a circumferential groove for the reception of a rubber Washer or ring. However, the invention is adapted for use in connection with any class of cans and is not confined to those used in connection with the vacuum process of sealing.

In order to comprehend the invention, reference should be had to the accompanying sheets of drawings, wherein- Figure 1 is a side view in elevation of the machine; Fig. 2, a detail View of the lever and actuating-cam for imparting reciprocating movement to the retaining-disks; Fig. 3,

a top plan view of the mechanism disclosed in Fig. 1 of the drawings, the chutes for the can-body and ends being removed; Fig. 4, an enlarged detail View of the can-body prior to being crimped and the bottom applied thereto; Fig. 5, a broken enlarged detail view of the can-body with its bottom applied thereto and head end crimped; Fig. 6, an end view of the mechanism disclosed in Fig. 1 of the drawin gs Fig. 7 ,an enlarged sectional part-broken plan View of the crimping mechanism, the can-body being illustrated held within the slots of the receiving and retaining disks and in position for being crimped and having its bottom applied thereto; Fig. 8, an enlarged detail View of the outer end of the crimper mechanism; Fig. 9, a similar view of the inner end thereof; Fig. 10, a detail View of the piston carrying the crimping-rollers and Fig. 11, a detail end view in elevation of the piston and its actuating means for applying the bottoms to the can-bodies, the receiving and retaining disks being illustrated by dotted lines.

Referring to the drawings, the numeral 1 is used to indicate the frame of the machine, within which work the can-body-receiving disks 2 2 and the retaining-disks 3 3. These disks are secured, respectively, to cross-shafts 4 5, to the outer ends of which shafts are attached the intermeshing gear-wheels 6 7, Figs. 1 and 3 of the drawings. Cross-shaft at works in bearings 8 of the frame, while cross-shaft 5 works in bearings 9 of the slide-blocks 10. Said blocks work in ways 11 of the said frame. From each slideblock projects a stud 12, which is engaged by the bifurcated end 13 of 1 the levers 14, which levers are fulcrumed to the frame 1.

The fulcrumed levers are actu-f ated by the wiper-wheels 15, secured to the drive-shaft 16, which shaft works through the frame of the machine and is driven bya drivebelt (not shown) working over belt-wheel 16.

During the rotary movement of the drive- 'shaft the wiper-wheels 15 are carried therewith and during a portion of their travel bear upon the lower ends of the fulcrumed levers IA and force the same downward or outward. The upper ends of the said lovers are thrown inward and move therewith the slide-blocks 10, so as to move the retaining-disks slightly toward the receiving-disks. The reason for such inward movement of the said disks will be hereinafter explained. As the wiper-wheel 15 moves out of engagement with fulcrumed levers 14 the slide-blocks are drawn outward by the pressure'of springs 17.

To the free end of the drive-shaft 16 is socured the crank-arm 18, which carries the roll 19. This roll works in and out of the in clined slots 20, cut in the periphery of the drive-disk 20, which disk is attached to crossshaft at. By means of the crank-arm 18 an intermittent or step rotation is imparted to the disk 20 and its shaft 4 from the continuously-rotary movement of the drive-shaft.

As the motion of cross-shaft 4 is transmitted to shaft 5 through the medium of the intergiven to the receiving and retaining disks.

In the periphery of the receiving-disks is formed a series of semicircular seats or sock .1 ets 21 and in the periphery of the retaining, Q" disks a series of similar seats or sockets 22.

These seats or sockets register during the movement of the receiving and retaining disks or the oppositely-operating mechanisms and hold the can -bodies 23 therein during the operation of placing the bottom thereon and crimping the head end thereof.

The can-bodies 23 are delivered one at a time to the receiving-disks by the chute 24, being held within the semicircular seat thereof until the retaining-disks engage therewith by means of the curved guard-plate 25. At the same time the bottoms 25' are supplied to the machine by runway 26, the lowermost bottom resting immediately in advance of piston 27, being supported by pin 26, secured in socket 27 of the piston-slide 27 forced outwardly by springs28. This piston Works in ways 28 of theframe, Fig. 11 of the drawings, and is moved inward and outward or reciprocated transversely of the machine by means of the cam-wheel 29, secured to the drive-shaft 16. In the periphery of camwheel 29 is cut the cam-groove 30, within which rests the roll 31, attached to stud 32, depending from the slide of piston 27. Being thus united, the piston is forced inward and outward during the rotary movement of the cam-wheel 29. As moved inward the piston removes the bottom 25 from its seat and forces the same onto end a of the can-body 23. \Vhile the bottom is being applied the can-body is held by the receiving and retaining disks within the seats 21 22 of the said disks. Inasmuch as the head end a of the can-body 23 is crimped during the operation of applying the bottom thereto it is required I that the said body be firmly held between bodies is concerned.

the receiving and retaining disks. Ordinarily a slight distance exists between the periphery of these disks, which is immaterial so far as applying bottoms onto the can- I-Iowever, in order to properly crimp the can-body it is required that the receiving and retaining disks be held firmly together, so as to completely close the can-body seats in order that the inner wall thereof may bear upon the can-body at all points. This closure of the can-body seats of the receiving and retaining disks is caused by a slight inward movement being permitted to the slide-bearing blocks 10, which are forced inward by contact of the wiper-wheels 15 with the lower end of the fulcrumed levers 14, as before explained. The inward movement of the slide-blocks takes place while I the disks are at rest or during the step rotation thereof. The retaining-disks are held pressed against the receiving-disks sufdciently long to enable the bottom to beapplied tothe retained can-body and the head endto be crimped. After the head end has been crimped the wiper-wheels move from off the fulerumed levers and by the pressure of springs'17the slide-block returns to its normal positi-on,-so as to place the retaining-disks a slight distance away from the receivingdisks, thus giving clearance for rotation of the said disks. The disks are then given a step rotation in order to gradually open or separate the seats within which rests the crimped and bottomed can-body and permit its discharge into chute or runway 33.

The head end a of the can-body is crimped within the machine for the purpose of providing a circumferential shoulder b and an annular groove-b, which groove terminates in an upright flange 17 Fig. 5 of the drawings. To enable the can-body to be thus crimped, the outer edge of the semicircular seats 21 22 of disks 2 3 is chamfered, as shown at d, Fig. 7 of the drawings, and formed with the groove d. When the disks are held together to clamp the can-body, this portion ofthe seats serves as a male die for the crimping-rolls 34. There are preferably four of these crimping-rolls, each being secured to a slide-block 35, fitted to move within the grooved end of the piston 36, Fig. 9 of the drawings. The piston 36 works within the casing 37, and the crimping-roll blocks are held normally pressed inward'by means of the springs 38, interposed between the said blocks and the inner wall of the casing 37, Fig. 7 of the drawings.

To the outer end portion of piston 36 is secured the pinion 39, which'pinion meshes with gear 40, secured to the drive-shaft 16. The rotary motion of said drive-sh aft is thus trans mitted to the piston 36. Said piston is held within its casing by a suitable collar. The casing is reciprocated transversely by means of the cam-wheel 42, secured to the driveshaft 16, Fig. 6 of the drawings, which wheel is formed with a peripheral cam-groove 43, within which works the roll 44, secured to a stud depending from the casing. Cam-Wheel 42 works in unison with cam-wheel 29. Consequently the crimper-piston 36 is moved inward, so as to place the crimper-rolls 34 within .the open head end of the can-body at the same time piston 27 is forced inward to apply the bottom thereto.

Through the crimper-piston 36 works the expander-rod 44, which rod when moved inwardly gradually forces the slide-blocks 35 apart or away from each other, so as to cause the crimping-rolls 34 to bear against the inner Wall of the can-body and crimp the head end thereof, as desired. stood that the periphery of each crimpingroll 34 corresponds with the shape of the maledie portion of the can-body seats. The outer end of the expander 44 is loosely fitted within cross-head 45, so as to rotate with the crimper-piston when moved inward to expand the slide-blocks 35, being held to the crosshead by collars on either side thereof. Said expander is moved inward and outward by meansof roll 49, secured to a stud depending from cross-head 45. This roll works within cam-groove 48, cut in the periphery of wheel 47, which wheel is attached to drive -'shaft 16 and rotates therewith. The crimper-piston being driven from the drive-shaft by the It will be under intermeshing gears is a continuously-rotating one.

In operation the various parts are so arranged or timed as to movements that the can-body is first received and held between the receiving and retaining disks, after which the retaining-disks are forced firmly against the receiving-disks while the disks are at rest. The piston 27 is then moved inward in order to force the can-bottom from within its seat 26 onto the held can-body, while at the same time the crimper-piston is moved inward, so as to place the crimper-rolls within the head end of the can. The moment the crimper-rolls enter the can-body expanderrod 44 is carried inward within its piston and the slide-blocks 35 forced outward laterally, cansingthe crimper-rolls to bear upon the inner wall of the held can-body and crimp the same against the male die. The parts then, through the medium of the respective devices, are restored to their normal positions and a step movement imparted to the receiving and retaining disks. The canbody being released by the movement of said disks falls into the discharge-chute Having thus described the invention, what is claimed as new,and desired to be protected by Letters Patent, is
